Robb has some new sights for his Glock 20. Generally speaking, the sights are the one thing that I think should be mandatory to replace on Glocks; the front sight is insultingly fat, the rear sight notch is far too narrow, and they’re cheap and plastic. Robb now has probably the best pistol sight for the Glock, the Sevigny Competition sights. You want a lot of light coming in around that front post so you can establish the proper relation between front and rear sight, and the Sevigny sights definitely do that. Available with all black posts or a fiber optic front sight, you can purchase them for an extremely reasonable price from our good friends at Brownells.
